High Tech Mother Goose

Mother McGee went to drive C:
  to find her poor Windows a byte
But, when she enquired, all drive space expired
  And not even Stacker would put it right.

Little Miss Muffet opened her notebook
  and called on WordPerfect to write
Along came a spider, who sat down beside her,
  and explained how the function keys worked.

Jack and Jill are married still
  but things look kinda scary
He loves a PC; she’s fond of a Mac
  and RISC makes both of them wary.

Mary had a little Lan
  Then, she wanted more
First she bought a lot of RAM
  Then part interest in a computer store.
